Effects of Intravenous Patient-Controlled Analgesia with Morphine, Continuous Epidural Analgesia, and Continuous Three-in-One Block on Postoperative Pain and Knee Rehabilitation After Unilateral Total Knee Arthroplasty

摘要: In this study, we assessed the influence of three analgesic techniques on postoperative knee rehabilitation after total arthroplasty (TKA). Forty-five patients scheduled for elective TKA under general anesthesia were randomly divided into groups. Postoperative analgesia was provided with i.v. patient-controlled (PCA) morphine in Group A, continuous 3-in-1 block B, and epidural C. Immediately surgery, groups started identical physical therapy regimens. Pain scores, supplemental analgesia, side effects, degree maximal flexion, day first walk, duration hospital stay recorded. Patients Groups B C reported significantly lower pain scores than those A. Supplemental comparable Compared A C, a incidence effects noted B. Significantly better flexion (until 6 wk surgery), faster ambulation, shorter However, these benefits did not affect outcome at 3 mo. We conclude that, TKA, provide relief PCA morphine. Because it induces fewer should be considered technique choice. Implications: determined arthroplasty, loco-regional (epidural or block) causes is
